On August 11, 2015, the Spearhead Pipeline which runs parallel to the Flanagan South Pipeline and shares a right of way, released an estimated 16-20 gallons of crude oil into a local intermittent creek in Shelby County, Missouri. The Spearhead is also owned by Enbridge and has carried crude oil across Missouri for the past 50 years. Both pipelines were shut off and a clean-up crew was sent to the site. Part of the Spearhead pipeline was excavated for inspection to determine the cause of the spill as the release point was unknown at the time of the spill.
The Missouri Department of Natural Resources reported that no fish kill occurred. Nor was any oily vegetation observed downstream. The Flanagan South pipeline was put back into operation the next day while efforts to investigate the Spearhead remained underway.
